The direct C-glycosylation of phloroacetophenone with an unprotected d-glucose in aqueous media using scandium(III) trifluoromethanesulfonate (Sc(OTf)3) as the catalyst, gave mono- and bis-C-beta-glycosylic compounds in highest total yield of 81%. The second and third use of the recovered Sc(OTf)3 afforded them in total yields of 56% and 53%, respectively.
以三氟甲磺酸钪（Sc(OTf)₃）为催化剂，在水介质中使间苯二酚苯乙酮与未保护的d-葡萄糖直接进行C-糖基化反应，得到单-C-β-糖苷化合物和双-C-β-糖苷化合物，总产率最高可达81%。回收的Sc(OTf)₃第二次和第三次使用时，其总产率分别为56%和53%。
